Backend Async Microservice

Build asynchronous backend microservices as listener-based Spring Boot services that consume Kafka messages or platform events, validate and map payloads, and orchestrate business behavior through services and adapter/shared libraries. The JIRA, event contract, schema, topic, and acceptance criteria context should already be present in the task context; use that provided context as the source of truth.

Expected Repository Shape

Treat the repo as a Maven Java 25 Spring Boot service.
